“It’s pretty incredible,” said Christopher, 24, about his YouTube success. “I’m very grateful for the Internet.”

“Lost Highway,” by Randal Myler and Mark Harelik, traces country music legend Hank Williams’ rise from his beginnings on the Louisiana Hayride to his triumphs at the Grand Ole Opry to his eventual self-destruction at age 29.

Along the way, the show features all of Williams’ iconic hits: “Lovesick Blues,” “I’m So Lonesome I Could Cry,” “Move It on Over,” “Hey, Good Lookin’,” “Your Cheatin’ Heart” and many others.

Williams’ catchy tunes have an enduring appeal and have charmed generations, Christopher said.

“It’s really a great show, and we’re having a blast,” said Christopher, a native of Houston.

Christopher learned about Flat Rock’s production of “Lost Highway” when he was in Canada, starring in “The Buddy Holly Story.”

“It was just happenstance that I found out that Flat Rock was looking for a Hank,” Christopher said. “I put a couple of Hank Williams songs on YouTube, and within 48 hours I had an offer.”

The show requires a 10-member cast of actor/musicians. Christopher plays guitar and sings like Williams. Most of the other actors portray the musicians who knew and worked with Williams.

“Hank Williams led a very difficult, tragic life,” Christopher said. “That lends itself to having a touching story. The music is really well-integrated. You see how his life shaped his music and how the music got darker and darker. It’s the best jukebox musical I’ve ever seen.”

Christopher himself has had a taste of the meteoric rise that Williams knew. Only three years ago, Christopher was working in Lubbock, Texas, as an emergency medical technician, with plans to be a doctor. An audition for “The Buddy Holly Story” changed all that. Now he’s a professional actor living in New York City.

“I’m the happiest I’ve ever been, doing this,” Christopher said.
